Fig. 1 is a terminal device access control method according to a first embodiment of the present invention. The terminal equipment access control method is applied to multimedia broadcast control equipment comprising an embedded processor, the multimedia broadcast control equipment further comprises a network communication module electrically connected with the embedded processor, and the terminal equipment access control method comprises the following steps:
s10, receiving the data packet;
s12, judging whether the data packet comes from the network communication module; and
and S14, responding to the determination that the data packet comes from the network communication module, determining identification information of terminal equipment corresponding to the data packet according to the packet header information of the data packet, and performing access control on the terminal equipment according to the identification information, wherein the terminal equipment is connected to the multimedia broadcast control equipment through the network communication module.
The identification information is, for example, Media Access Control (MAC) address information of the terminal device.
For the convenience of understanding the present invention, the following describes the access control method of the terminal device in the present embodiment in detail with reference to fig. 2, 3 and 4. The terminal device access control method of this embodiment is executed by an embedded processor of the multimedia broadcast control device. Wherein the embedded processor is, for example, an ARM embedded processor.
Fig. 3 is a multimedia broadcast control system, for example, including a multimedia broadcast control device 20 and a terminal device 30 electrically connected to a network communication module 26 of the multimedia broadcast control device 20. The multimedia playback device 20 can, for example, include a second network communication module 24, a network communication module 26, and an embedded processor 22 electrically connected between the second network communication module 24 and the network communication module 26. The network communication module 22 is, for example, a wifi module (hereinafter referred to as wifi AP module) in an AP (Access point) mode, and the second network communication module 24 is, for example, at least one of a wifi module, an ethernet module and a mobile communication module in a station mode. The mobile communication module includes a 4G communication module and a 5G communication module, which is not limited herein in the embodiments of the present invention. Of course, the network communication module 22 may not be limited to the wifi AP module, and may also be another network module capable of enabling the terminal device 30 to perform network connection through the wifi AP module, which is not specifically limited herein. The terminal device 30 is, for example, an electronic device such as a mobile phone, a notebook computer, a desktop computer, and the like that can access the hotspot network.
When the method for controlling access to a terminal device according to the embodiment of the present invention is executed, the embedded processor 22 first receives a data packet, then determines whether the data packet is from the network communication module 26, for example, a wifi AP module, and then, in response to determining that the data packet is from the network communication module 26 (that is, the data packet is sent by the terminal device 30 accessing the network communication module 26), determines identification information of the terminal device corresponding to the data packet, that is, the terminal device 30, according to header information of the data packet, and performs access control on the terminal device according to the identification information, where the identification information is MAC address information of the terminal device 30, and the terminal device is connected to the multimedia broadcast control device through the network communication module. In the technical scheme, access control is performed on the terminal device according to whether the data packet comes from the network communication module or not and according to the identification information of the terminal device corresponding to the data packet under the condition that the data packet comes from the network communication module, and compared with the prior art that the terminal device can be networked or access a user server through other network modules on the multimedia broadcast control device as long as the terminal device can access the first network communication module, the access control is performed on the terminal device in the embodiment of the invention, so that the access security of the multimedia broadcast control device can be improved.
In a specific embodiment of the present invention, as shown in fig. 2, the performing access control on the terminal device according to the identification information specifically includes: step S142, acquiring a pre-stored identification information set; step S144, judging whether the identification information set has target identification information matched with the identification information; step S146, in response to determining that the target identification information matching the identification information does not exist in the identification information set, determining whether the data packet needs to be forwarded to the second network communication module 24 according to the packet header information of the data packet; and step S148, in response to determining that the data packet needs to be forwarded to the second network communication module 24, discarding the data packet. In the technical scheme, the terminal device is determined to be an illegal user by determining that the identification information of the terminal device does not exist in the identification information set and the header information of the data packet indicates that the data packet needs to be forwarded to the second network communication module, so that the data packet is discarded, and thus, the safety problem of the user server caused by the fact that the illegal terminal device steals traffic by communicating with the second network communication module and attacks the user server can be prevented.
In a specific embodiment of the present invention, the method for controlling access to a terminal device further includes: in response to determining that the data packet does not need to be forwarded to the second network communication module 24, parsing the data packet, and prompting to log in a system of the multimedia broadcast control device 20, that is, an operating system of the multimedia broadcast control device (in the embodiment of the present invention, the operating system is, for example, an android operating system); in response to successfully logging in the system of the multimedia broadcast control device 20, storing the identification information of the terminal device 30 in the identification information set; or, in response to not successfully logging in the system of the multimedia play control device 20, discarding the data packet. In this technical solution, under the condition that it is determined that the data packet does not need to be forwarded to the second network communication module, the user is prompted to log in the system of the multimedia broadcast control device by parsing the data packet, so that an initial user can log in the system of the multimedia broadcast control device to become a legal user, and the identification information of the terminal device is stored into the identification information set while the log-in is successful, so that the terminal user can communicate with the second network communication module 24 and can access the operating system of the multimedia broadcast control device 20 when accessing the multimedia broadcast control device through the network communication module 26 next time.
In a specific embodiment of the present invention, the terminal device access control method further includes a system, in response to the target identification information matching the identification information in the identification information set, processing the data packet, allowing the terminal device 30 to communicate with the second network communication module 24, and allowing the terminal device 30 to access the multimedia broadcast control device 20. In this technical solution, when it is determined that the target identification information matched with the identification information exists in the identification information set, that is, when the terminal device is a valid user, the terminal device is allowed to communicate with a second network communication module, and the terminal device is allowed to access the system of the multimedia broadcast control device, thereby realizing effective access of the valid user.
Specifically referring to fig. 4, the method for controlling access to the terminal device includes:
the embedded processor 22 first receives the data packet, and then determines whether the data packet is from the wifi AP module, that is, whether the data packet is sent by the terminal device 30 connected to the wifi AP module of the multimedia broadcast control device 20;
if the embedded processor 22 determines that the data packet is not from the wifi AP module, the embedded processor 22 directly processes the data packet; if the data packet is determined to be from the wifi AP module, the embedded processor 22 determines, according to the packet header information of the data packet, the identification information of the terminal device corresponding to the data packet, for example, the MAC address information for uniquely identifying the terminal device 30;
then, the embedded processor 22 determines whether the MAC address information is stored in the multimedia broadcast control device 20, specifically, in this embodiment, the MAC address information of a legitimate user, that is, an authorized terminal device, is stored in the embedded processor 22 or a nonvolatile memory, such as a flash memory, electrically connected to the embedded processor 22, and when the embedded processor 22 executes this determination process, first, an identification information set pre-stored in the embedded processor 22 or the nonvolatile memory is obtained, and then, it is determined whether the identification information set has identification information matching the MAC address information of the terminal device 30;
then, in the case that the MAC address information is stored in the multimedia play control device 20, the embedded processor 22 processes the data packet and allows the terminal device 30 to communicate with other network modules of the multimedia play control device 20 except for the wifi AP module, such as a second communication module, and allows the terminal device 30 to log in the system of the multimedia play control device 22 to operate the multimedia play control device 22,
in the case that the MAC address information is not stored in the multimedia playback device 20, the embedded processor 22 determines whether the data packet needs to be forwarded to the second network communication module 24 according to the packet header information of the data packet. If the data packet needs to be forwarded to the second network communication module 24, the embedded processor discards the data packet, so that, in the case that it is determined that the terminal device 30 is an illegal user, by discarding the data packet, the connection between the terminal device 30 and the multimedia play control device 20 is disconnected, the terminal device 30 can be prevented from stealing user traffic, and the terminal device 30 can be prevented from accessing a server of the user, of course, the embedded processor 22 can also control to disconnect the connection between the terminal device 30 and the multimedia play control device 20 in the case of performing the discarding the data packet. If the embedded processor 22 determines that the data packet does not need to be forwarded to the second network communication module 24 according to the packet header information of the data packet, that is, the destination receiving address of the data packet corresponds to the wifi AP module, the embedded processor 22 analyzes the data packet, and prompts the user to log in a system of the multimedia broadcast control device. In response to a successful user login, indicating that the user is an initial user, the embedded processor 22 stores the MAC address information of the terminal device 30 (for example, the identification information set stored in the embedded processor 22 or the non-volatile memory), in which case, the terminal device 30 is a valid user, and in the case that the MAC address information is stored in the multimedia broadcast control device, the embedded processor allows the terminal device to communicate with other network modules except for the wifi AP module, for example, a second network communication module. If the user login fails, it indicates that the terminal device 30 is an illegal user, the embedded processor 22 discards the data packet, and in the case of discarding the data packet, the embedded processor 22 may control to disconnect the terminal device 30 from the multimedia broadcast control device 20.
It should be noted that, the identification information set may be pre-stored in the multimedia broadcast control device in the following manner: a user logs in the multimedia playing and controlling device through configuration software installed on a PC or a mobile terminal, such as Viplex express software of Norwa, connects a target terminal device with a wifi AP module of a display screen controller, and then stores an MAC address of the target terminal device in the multimedia playing and controlling device.
In summary, the terminal device access control method provided in the embodiments of the present invention first receives a data packet, then determines whether the data packet is from a network communication module, then determines, in response to determining that the data packet is from the network communication module, identification information of a terminal device corresponding to the data packet according to header information of the data packet, and finally performs access control on the terminal device according to the identification information, so that access control on a terminal device that accesses a multimedia broadcast control device through a network communication module is achieved, a traffic theft by an illegal user can be prevented, and a server associated with the multimedia broadcast control device is protected from being secure.
